My classification of eccentric cam types is convenient but admittedly somewhat arbitrary. Rather than try to explain it solely in words, I'll provide this chart of typical examples:
Class | Examples |
---|---|
Plate | |
Drilled Plate | |
Perforated Plate | |
Open | No web, etc. inside the cam. |
Semi-open | One smaller opening, no thin web. |
Open-web | Minimal web inside the cam. |
Asymmetrical Open-web |
Back side of cam is angled. |
Semi-open Web |
More substantial web but with only one opening. |
Semi-web | Multiple holes in the web. |
Web | |
Braced | |
Drooped | Hybrid | More complex combinations. |
